The creep behaviour of fibre reinforced plastics [PDF]

open access: yes, 1969
Synopsis: This paper describes the tensile creep behaviour of fibre reinforced plastics under a uniaxial stress system. In particular, unidirectionally and bidirectionally reinforced plastics are considered for the relative ease with which samples of

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Characterization of Polymer Surfaces by the Use of Different Wetting Theories Regarding Acid-Base Properties

open access: yesInternational Journal of Polymer Science, 2017
The existing wetting methods for the determination of acid-base properties on solid surfaces are discussed. Striving for a better understanding of the adhesive polymer interactions in adhesively joined polymers, the methods of Berger and van Oss ...

Biophysical analysis of angiotensin II and amyloid‐β cross‐interaction in aggregation and membrane disruption

open access: yesFEBS Letters, EarlyView.
Angiotensin II (AngII), a neuropeptide, interacts with amyloid‐β (Aβ), a key player in Alzheimer's disease. This study reveals that AngII reduces Aβ aggregation and membrane disruption in vitro. Biophysical assays and molecular modeling suggest AngII binds disordered Aβ forms, potentially modulating early amyloidogenic events and contributing to ...

Interfacial nanocomposite sensors (sQRS) for the core monitoring of polymer composites’ fatigue and damage analysis

open access: yesNanocomposites, 2018
The quick development of the smart factory and prognostic and health management (PHM), in the fields of aeronautic, automotive and green energies, is evidencing a need for sensors able to monitor the behavior of composite materials all along their life ...

Bond–slip Behavior of Fiber-reinforced Polymer/concrete Interface in Single Shear Pull-out and Beam Tests [PDF]

open access: yes, 2015
It has been assumed that the fiber-reinforced polymer/concrete interface is subjected to in-plane shear condition when intermediate crack debonding failure occurs.

Linked dimers of the AAA+ ATPase Msp1 reveal energetic demands and mechanistic plasticity for substrate extraction from lipid bilayers

open access: yesFEBS Letters, EarlyView.
Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

Application of Tegeran (Maclura cochinchinensis) bark as natural tanning agent for the quality of tilapia fish skin

open access: yesMajalah Kulit, Karet, dan Plastik, 2019
Chrome is a tanning material that is very harmful to the environment hence its role is being replaced with vegetable tanning materials. One of the natural ingredients that contain tannin is Tegeran (M. cochinchinensis) wood.

A Simple Methodology to Better Appreciate Structures in Mandibular Angle Fractures Using 3-Dimensional Reconstruction Software [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2019
Introduction: In Singapore, fractures of the mandible are common and of which, 32% occur at its angle. Current TwoDimensional (2D) imaging methods are lacking in accuracy, leading to increased surgical morbidity.
